Can You Sleep in the Car with the Heater On?

[OBeau]

You should not sleep in the car with the heater on. When the car's heater is running in recirculation mode, carbon monoxide emitted by the engine can enter the cabin through the air conditioning system. With the windows closed, the concentration of carbon monoxide inside the car can gradually increase, potentially leading to poisoning. 1. Types of car heaters: They can heat either the air inside the car or air drawn from outside, raising the interior temperature. Car heating systems come in various types, classified by heat source into hot water heating systems, gas heating systems, exhaust heating systems, etc. Currently, most passenger cars primarily use hot water heating systems. 2. Functions of car heaters: The car heating system provides warmth to the cabin. When there is a significant temperature difference between the inside and outside of the car, frost or fog may form on the windows, obstructing the driver's view and compromising driving safety. Activating the heating system can help remove frost and fog from the windows.
